I've installed Ubuntu 11.4 on my dell xps m2010 using wubi. Then booted up and could not connect to the Internet using 3three huawei e122 usb mobile broadband (I would like this to work also).

I've managed to connect through a wireless network, I went to my favorite sites and was told I needed to install adobe flash player.This what I did players run and picture is good. But there is no sound!

Then I've tried to play songs in Banshee, but no sound.

I have checked everything in sound preferences including test speaker, there is sound. I have sigmatel sound card.
